Why does a few G's in mobile phone memory indicate insufficient memory?

The phone prompts that the memory is full/insufficient or needs optimization. We recommend that you:

1. Delete unnecessary data and applications: Intelligent Manager (memory manager)-storage space/memory.

2. Close unneeded applications: click the recent task key in the lower left corner of the screen-click the "X" in the upper right corner of the application to be closed/close all the applications below.

3. If the mobile phone supports the memory card, move the multimedia file to the expansion card or set the shooting storage path as the expansion card. If there is no memory card, it is recommended to move multimedia files to the computer regularly.

4. Uninstall uncommon software or files.

If the memory of the mobile phone is still insufficient after the above operation, it is recommended to back up data (contacts, information, photos, etc.). ) and try to restore the factory settings.
